Massachusetts Emergency Management Agency issued the bulletin below on Tuesday's weather event.  It appears to concern off-Cape interests more than those here.  Use caution if traveling tomorrow.

Wintry Mix Tuesday/Tuesday Night

For areas south of the Mass Pike, a mix of snow, sleet and freezing rain is expected to move in around daybreak Tuesday, quickly changing to rain in the southeast and along the south coast. Pockets of freezing rain may persist closer to the Mass Pike into the afternoon. North of the Mass Pike, snow is expected to develop around daybreak Tuesday, gradually changing to sleet and freezing rain during the afternoon. Precipitation changing to all rain Tuesday evening, with pockets of freezing rain, will continue across the higher terrain. There is also a low risk for some freezing rain across portions of northeast MA Tuesday night.

PRECIPITATION AMOUNTS
• Snow: 2 to 4 inches of snow could occur north of the Mass Pike with the highest amounts north of Rt. 2 near the New Hampshire border. A coating to 1 inch of snow south of the Mass Pike.
• Ice: A trace to 0.10" ice accretion across interior MA. Potential for 0.10 to 0.25" across the east slopes of the Berkshires and northern Worcester Hills.
